A portion of I-80 will be closed for work on May 14 and May 15 
A stretch of Interstate 80 in the City of San Pablo will be closed to all traffic for eight hours overnight on May 14-15. 

All lanes between San Pablo Avenue and San Pablo Dam Road will be closed starting at 11 p.m. May 14 until 7 a.m. May 15. 

The Contra Costa Transportation Authority (CCTA), Caltrans, the Metropolitan Transportation Commission, and the City of San Pablo recently broke ground on an interchange improvement project on Interstate 80 at San Pablo Dam Road.

To facilitate the next phase of work, they must temporarily close this section of the freeway. 

Temporary detours will be in effect during the eight hour overnight period of closure (see the maps for details).


The closures will enable the placement of temporary support structures for the construction of a new pedestrian overcrossing at Riverside Avenue, which will replace the current overcrossing. 

The new overcrossing will extend across Amador Street, enhancing safety for Riverside Elementary School students and the community.
